<b>Title</b>: Difference between 1=1 and 3=3: Energy Gain Kernel for Climate Feedbacks
<div><br>
</div>
<div><b>Abstract: </b><span style="">This study introduces a climate feedback kernel, referred to as the “energy gain kernel” (EGK). The EGK allows for separating the net radiative energy perturbations given by a Planck feedback matrix explicitly into thermal
energy emission perturbations of an individual layer, and thermal energy perturbations absorbed by all layers in response to forcing in that layer. The formal is represented by the diagonal matrix of a Planck feedback matrix and the latter by EGK. Elements
of EGK are all positive, representing amplified energy perturbations at a layer where forcing is imposed and energy gained at other layers, both of which are achieved through radiative thermal coupling within an atmosphere-surface column. </span><span style="">Applying
EGK to input energy perturbations—whether external or internal due to responses of non-temperature feedback processes to external energy perturbations, such as water vapor and albedo feedbacks—yields their total energy perturbations amplified through radiative
thermal coupling within an atmosphere-surface column. </span><span style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">As the strength of EGK depends exclusively on climate mean state
information, it offers a solution for effectively and objectively separating control climate state information from climate perturbations for climate feedback studies. Given that an EGK comprises critical climate mean state information on mean temperature,
water vapor, clouds, and surface pressure, we envision that the diversity of EGK across different climate models could provide insight into the inquiry of why, under the same anthropogenic greenhouse gas increase scenario, different models yield varying degrees
of global mean surface warming.</span></div>
